The answer is .plist files, unified logs, and FSEvents. These three artifacts are foundational in macOS forensics because they capture distinct layers of system activity: unified logging records every system and application event in a centralized, searchable database; .plist files store application preferences, configuration data, and user settings that can reveal persistence mechanisms or malicious modifications; and FSEvents maintain a detailed history of file system changes, including timestamps and paths, which is invaluable for reconstructing user or malware behavior. On the Computer Hacking Forensic Investigator CHFI exam, this question tests your ability to distinguish macOS-specific artifacts from Windows-only ones like Prefetch files, and to recognize that bash_history is not the default shell log for modern macOS (zsh is). A common trap is confusing shell history with system-level logging. To remember the trio, think of the acronym UFP: Unified logs, Filesystem events (.plist), and Path changes (FSEvents).
CHFI OS and Network Forensics Practice Question
This CHFI practice question tests your understanding of os and network forensics. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A forensic analyst is examining a Mac system for evidence of malicious activity. Which THREE artifacts are commonly analyzed in macOS forensics?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Unified logging
macOS forensics frequently examines unified logs (for system events), .plist files (for configuration and application data), and FSEvents (for file system change history). bash_history is not the default for macOS (zsh is default). Prefetch files are Windows-only.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Prefetch files
Why it's wrong here
Prefetch files are a Windows artifact.
✗
bash_history
Why it's wrong here
bash_history is for Linux; macOS uses zsh with .zsh_history by default.
✓
Unified logging
Why this is correct
Unified logging captures system and application logs in a centralized database.

✓
FSEvents
Why this is correct
FSEvents records file system changes and can be used for timeline analysis.

✓
.plist files
Why this is correct
Property list files store application preferences and configuration; they are a key artifact.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CHFI exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
